the first quarter of the match. On 22 October 2015 in a UEFA Europa League 3–2 home game against Plzeň, he scored a long-range goal, giving his club a lead of two goals. In January 2016, he announced he would not accept Rapid's offer to renew his contract which was set to expire in summer 2016 and would instead leave the Austrian club after three years. He left the club having 101 appearances (7 goals, 6 assists) in all competitions. Werder Bremen A few days later Petsos signed a contract until summer 2019 with German club Werder Bremen. On 11 September 2016, he made his debut with the club as a substitute in a 2–1 home loss against Augsburg.
